Lactose intolerance is very common in adults. It is rarely dangerous. Around 30 million American adults have some degree of lactose intolerance by age 20. 1  In Caucasians, lactose intolerance often develops in children older than age 5.  In African Americans, the problem can occur as early as age 2.
The winter flounder is one of five species in the genus Pseudopleuronectes along with the Yellow-striped flounder, Cresthead flounder, Marbled flounder, and Dark flounder. It is the only cogener to inhabit the Atlantic Ocean.
At this same time, the left side develops its dark color and the right side turns white. Male and female southern flounder are almost like two different species of fish. Males grow slower and have a short life span, almost never living over 3 years old or growing over 14 inches long. Females live longer and can grow to 28 inches. Also, after their first year of life, males live mostly in offshore waters.
